Abstract
Abstract An antenna (20) including a continuous planar conductor (22) in a coaxial connector. The planar conductor (22) is made by stamping an array of slots (30) in a continuous sheet of metal with ends of adjacent slots (30) being offset from each other in an alternating pattern of long and short slot portions (32, 36) on each side of a centerline of the array; at least filling each slot (30) with a dielectric material (50), thereby defining a slot filled strip; and cutting along each side of the slot-filled strip intersecting each filled long slot portion (32) at a sufficient distance from the ends of adjacent ones of the filled short slot portions (36) to define a strap (42) of metal connecting the metal strips on each side of each slot (30).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A flexible antenna comprising: a planar conductor stamped from a metal sheet and having a contact section at one end thereof and a plurality of substantially parallel metal strips, each successive strip being connected at one end to an adjacent previous strip and at the other end to the next strip by a metal strap to define a continuous conductor; a contact lead electrically and mechanically secured to said contact section defining a termination; dielectric material molded over selected areas of said conductor including over and between said strips and said termination defining selected insulated areas and an insulated termination, at least one of said selected insulated areas defining an insulating pad adapted to receive a ground conductor; said ground conductor being disposed on said at least one insulating pad; and a conductive shell disposed over said insulated termination of said planar conductor, said shell being in electrical engagement with said ground conductor, said lead, insulation and shell defining a coaxial connector.
Claim 2
Dependent Claim
162 words
A flexible antenna comprising: a planar conductor stamped from a metal sheet and having a contact section at one end thereof and a plurality of substantially parallel metal strips, each successive strip being connected at one end to an adjacent previous strip and at the other end to the next strip by a metal strap to define a continuous conductor; a contact lead electrically and mechanically secured to said contact section defining a termination; dielectric material molded over selected areas of said conductor including over and between said strips and said termination defining selected insulated areas and an insulated termination, at least one of said selected insulated areas defining an insulating pad adapted to receive a ground conductor; said ground conductor being disposed on said at least one insulating pad; and a conductive shell disposed over said insulated termination of said planar conductor, said shell being in electrical engagement with said ground conductor, said lead, insulation and shell defining a coaxial connector.
Claim 3
Dependent Claim
20 words
The flexible antenna of claim 1 further including a resilient sleeve-like member disposed over said conductor and said conductive shell.
Claim 4
Dependent Claim
47 words
The flexible antenna of claim 1 wherein said contact lead is part of an electrical contact, said antenna further including a discrete dielectric sleeve disposed over said contact lead and an adjacent portion of said contact, said sleeve being dimensioned to be received inside said conductive shell.
Claim 5
Dependent Claim
20 words
The flexible antenna of claim 1 wherein said lead is electrically and mechanically secured to said contact section by soldering.
Claim 6
Dependent Claim
20 words
The flexible antenna of claim 1 wherein said lead is electrically and mechanically secured to said contact section by crimping.
Claim 7
Dependent Claim
36 words
The flexible antenna of claim 1 wherein said contact lead includes a bore extending axially into said lead from a forward end thereof, said bore being dimensioned to receive said contact section of said planar conductor.
Claim 8
Dependent Claim
20 words
The flexible antenna of claim 5 wherein said lead is electrically and mechanically secured to said contact section by crimping.
